It asserts a reset signal on power-up and holds it low for a minimum of 90 ms after the supply crosses the threshold, giving the system time to stabilize before the processor starts executing code. This output type lets multiple supervisors share a common pull-up resistor on a shared reset line, which is common in multi-rail systems. The voltage threshold is adjustable/selectable via external resistors, so the same part number can be configured for different supply rails (e.g., 3.3 V, 2.5 V, 1.8 V) by changing the divider network. This reduces SKU count for a design that monitors multiple voltages. Housed in a 5-pin SOT-23 (SC-74A) package, the MAX6457UKD3A+T occupies minimal board area and suits space-constrained designs. The SOT-23-5 footprint is widely used and easy to route on two-layer boards. Surface-mount mounting and tape-and-reel packaging support automated assembly. The reel format is standard for volume production; cut-tape options are available for prototypes. ## Temperature grade and environment This makes it suitable for outdoor telecom, motor drives, and under-hood automotive applications where the ambient temperature can exceed 85°C.","metaTitle":"MAX6457UKD3A+T Simple Reset/Power-On Reset, SOT-23-5","metaDescription":"MAX6457UKD3A+T simple reset/power-on reset IC, active-low open-drain output, 90ms min timeout, SOT-23-5, -40°C to +125°C.
